Apparatus for producing cigarette packs provided with coupons
During the production of (cigarette) packs by packers ( 13 ), the pack, depending on its configuration, has printing carriers, namely coupons which may be folded a number of times, added to it. These are produced by a coupon-production device ( 16 ) in a coupon arrangement ( 15 ) and are introduced into containers, namely magazines ( 20 ), in a filling station ( 18 ). A number of these magazines, in turn, which corresponds to requirements is kept on vehicles, namely transporting carts ( 42, 43 ), in order to be fed to the packer ( 13 ). The relevant machines and subassemblies are connected to a central control unit ( 91 ) which defines the quantity of coupons which are to be produced and causes the magazines ( 20 ) and/or the transporting carts ( 42, 43 ) to be coded, with the result that the supply of the packers ( 13 ) with coupons is controlled in accordance with the batch of packs which is to be produced.
1. An apparatus for handling coupons in the production of packs with at least one coupon applied to each pack, the coupon ( 11 ) having been folded a number of times, wherein the coupon is removed from a magazine ( 20 ), in a region of a packer ( 13 ) and fed to the pack, characterized by the following features:
a) the coupons ( 11 ) are produced by a coupon-production means ( 16 ) in a region of a separate coupon assembly ( 15 ),
b) the coupon-production means ( 16 ) is followed by a distributor system ( 17 ) for feeding the coupons ( 11 ) one after the other to a filling station ( 18 ),
c) upright magazines ( 20 ) are kept in a region of the filling station ( 18 ), wherein the coupons ( 11 ) are conveyed one after the other into the magazines ( 20 ), which are open at the top, by a filling conveyor ( 61 ), and wherein a coupon stack ( 19 ) is formed within each magazine ( 20 ), and
d) the magazines ( 20 ) filled with coupons ( 11 ) are set down on a transporting cart ( 42 , 43 ) for transporting a selected number of magazines ( 20 ) to the packer ( 13 ).
2. The apparatus as claimed in claim 1 , characterized in that a separate coupon assembly ( 15 ) comprises a coupon-production means ( 16 ), a following distributor system ( 17 ) and a subsequent filling station ( 18 ), wherein a plurality of coupons ( 11 ) are produced simultaneously in a region of the coupon-production means ( 16 ) and are fed separately and one after the other to the filling station or the filling conveyor ( 61 ) by the distributor system ( 17 ).
3. The apparatus as claimed in claim 1 , characterized in that the distributor system comprises a plurality of successive endless receiving belts ( 28 , 29 , 30 , 31 ), by means of which, as a result of different conveying speeds, a spacing is produced between the simultaneously produced coupons ( 11 ), intermediate conveyors ( 32 , 33 ) and connection conveyors ( 34 , 35 ), and a collecting conveyor ( 36 ) by means of which the coupons ( 11 ) which are fed in a plurality of paths are brought together into a common path for transfer to an entry conveyor ( 37 ).
4. The apparatus as claimed in claim 3 , characterized in that the coupons arriving one after the other, in a region of the entry conveyor ( 37 ) to the filling station ( 18 ), are distributed over at least two transfer conveyors ( 39 , 40 ), which are each assigned to one of two filling subassemblies ( 26 , 27 ).
5. The apparatus as claimed in claim 1 , characterized in that, in a region of the filling station ( 18 ), the upright magazines ( 20 ) are transported one after the other, by a magazine conveyor ( 55 ), into a filling location ( 59 ) beneath the filling conveyor ( 61 ), and in that the filled magazines ( 20 ) are conveyed by the magazine conveyor ( 55 ) into a subsequent closure station ( 66 ) for the purpose of applying a closure to an upwardly oriented open side of the magazine ( 20 ), for the purpose of applying a transversely directed closure tape ( 67 ).
6. The apparatus as claimed in claim 5 , characterized in that the tape ( 67 ) is applied to the top side of the magazine in a region of the closure station ( 66 ) by a tape subassembly ( 68 ), wherein the magazine ( 20 ) is conveyed relative to the tape subassembly ( 68 ) by the magazine conveyor ( 55 ) in order for the tape ( 67 ) to be applied.
7. The apparatus as claimed in claim 6 , characterized in that, in a region of the tape subassembly ( 68 ), the tape ( 67 ) is pressed onto side walls and onto the top side of the magazine ( 20 ) by a spring-biased press-on roller ( 80 ), wherein the press-on roller ( 80 ), which is movable counter to pressure is moved by the transported magazine ( 20 ) out of a press-on position for the tape on a side wall and over the top side of the tape while guiding the tape ( 67 ) in the process.
8. The apparatus as claimed in claim 7 , characterized in that tapes ( 67 ) are arranged on a continuous carrier band ( 78 ), and in that the spring-biased press-on roller ( 80 ) butts against the carrier band ( 78 ) on a side thereof which is directed away from the tapes ( 67 ).
9. The apparatus as claimed in claim 6 , characterized in that the tape ( 67 ) is folded in a U-shaped manner around a top side of the magazine ( 20 ), with a leg ( 73 ) on one side and an endpiece ( 74 ) on the opposite side, two press-on elements causing the tape ( 67 ) to be transferred from the carrier band ( 78 ) to the magazine, said elements comprising the press-on roller ( 80 ), on the one hand, and a separately moveable pressure-exerting roller ( 84 ), on the other hand.
10. The apparatus as claimed in claim 5 , characterized in that arranged in a region of the filling station ( 18 ), following the closure station ( 66 ) for applying the tape ( 67 ), is a printing unit ( 89 ) for applying production-related data or codes to the tape ( 67 ).
11. The apparatus as claimed in claim 1 , characterized in that the magazines ( 20 ) filled in a region of the filling station ( 18 ) are removed from the filling station ( 18 ) and set down, on a bearing plate ( 45 ) of a transporting cart ( 42 , 43 ), by a gantry-type conveyor ( 47 ), the gantry-type conveyor ( 47 ) comprising two longitudinal members ( 48 , 49 ), a transverse member ( 50 ), which is movable along the longitudinal members ( 48 , 49 ), and a carrying arm ( 51 ) which is movable up and down on the transverse member ( 50 ) and has a holder ( 53 ) for magazines ( 20 ).
12. The apparatus as claimed in claim 1 , characterized in that the coupon-production means ( 16 ), and/or a printer ( 89 ) and/or the packer ( 13 ) and/or a reader ( 90 ) for markings on the magazines ( 20 ) are connected to a control unit ( 91 ) for controlling the coupon production in dependence on requirements in a region of the packer ( 13 ) and for corresponding coding of the magazines ( 20 ) and/or of the transporting cart ( 42 , 43 ).
